Answer:
x=4, y=9
Step-by-step explanation:
Solve with substitution.
Answer:
y = - x +
Step-by-step explanation:
The angle between the tangent and the radius at point P is 90°
Calculate the slope of the radius m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (8, 15)
m = =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + b ← is the partial equation
To find b substitute (8, 15) into the partial equation
15 = - + b ⇒ b = 15 + =
y = - x + ← equation of tangent
